Installing a PFC500/E
This chapter describes the Profile XP Fibre Channel RAID Storage Chassis (PFC 500/E)
installation requirements and procedures. Major topics are:
• Requirements
• Rack mounting a PFC 500/E
• PFC500/E powerup and initialization
• PFC500/E powerdown
• Binding disk modules into groups
Requirements
This section explains site, cabling, and addressing requirements.
Site requirements
For proper PFC500/E operation, the installation site must conform to certain
environmental specifications. These are detailed below and in Appendix A.
Power
To determine a PFC500/E’s power requirements, use the power rating on the chassis
label. This rating is the maximum power required for a fully loaded chassis. The input
current, power (VA), and dissipation for the PFC500/E are based on the maximum
capability of the power supplies and cooling system to provide internally regulated
power. Typical values will be less depending on the number and manufacturer of disk
drives and activity level. These values represent either the values for the power cord of
a PFC 500/E with a single power supply, or the total values shared by the line cords of
two power supplies in the same PFC 500/E, with the division between the power cords
and supplies at the current sharing ratio. If one of the two power supplies fails, the
remaining supply and cord support the full load. You must use a rack mount cabinet with
ac power distribution, and have main branch ac distribution that can handle these values
for the number of PFC500s and PFC 500Es that you will interconnect.
Cooling
The ambient temperature specification is measured at the front door inlet. The site must
have air conditioning of the correct size and placement to maintain the specified ambient
temperature range. The air conditioning must be able to handle the BTU requirements of
the PFC 500s and any connected PFC 500Es.
